PolarTransforms {beadarraySNP} | R Documentation

## Polar transformations

### Description

Perform polar transforms on Illumina Golden Gate bead arrays

### Usage

       RG2polar(object,trig=FALSE)
       polar2RG(object,trig=FALSE)

### Arguments

`object` | SnpSetIllumina object
`trig` | Logical, use geometric distance intensity. Otherwise use addition of intensities

### Details

`RG2polar` transforms the `R` and `G` matrices to `theta` and `intensity` matrices. Note that the intensity value is the sum of `R` and `G` and not the geometric distance to the origin.

`polar2RG` performs the reverse transformation

### Value

This function returns an `SnpSetIllumina` object.

      data.polar<-RG2polar(chr17.260)
      plot(assayData(data.polar)$theta,assayData(data.polar)$intensity)
